Kinetics and Spectroscopy of BrNO
Abstract
The infrared spectra and photochemistry of nitrosyl bromide, BrNO, are important to characterizing the performance of a recently demonstrated Br((2)P1/2)-NO(v=2--> v=1) transfer laser pumped by photolysis of iodine molecules. This wavelength agile, mid-infrared laser may be a desirable source for remote sensing and infrared countermeasures missions. Nitrosyl bromide also plays a role in the destruction of stratospheric ozone. The kinetics of BrNO formation and destruction were examined using time-resolved photolysis techniques. The equilibrium constant for the dark reaction Br2 + 2NO (reversible reaction) 2BrNO was determined as Ksub eq 168 + or - 23 /atm and the rate constant for the forward reaction as k sub f = 1.40 + or - .18 x 10(exp -38) cm to the 6th power/sq molecule/s at 293K. A novel technique for the fitting of the observed time profiles to the three-body kinetics was developed which utilizes the complete temporal profile to establish the rate coefficients.
